# Run a node with Docker
## Environment
Ubuntu/CentOS and other systems (including Windows 10 Professional Edition, similar commands) with Docker installed, and docker is running.
## Run a node
Run the following command to run the node:
```shell
$ sudo docker run --restart=always \
--name starcoin-main \
-d -p 9880:9880 \
-v /data/starcoin/:/data/starcoin/ \
starcoin/starcoin \
/starcoin/starcoin \
-n main \
-d /data/starcoin \
--disable-metrics true \
--stratum-address 0.0.0.0 --stratum-port 9880 \
--miner-thread 0
```
> Hint:
>
> * If you don't need to start the mining pool function, you can remove -p 9880:9880, and the last parameter --stratum-address 0.0.0.0 --stratum-port 9880;
> * -n main: Specify the main network main, the test network can be changed to barnard;
> * \--miner-thread 0: The number of mining threads, which can be adjusted by yourself;
Check the running status of the node:
```
$ sudo docker ps -a
